Show how deadlocks may be modeled using Petri Nets?

Answer 1

Deadlocks can be modeled using Petri Nets by representing processes as places and resources as transitions. In this model, tokens in the places signify the availability of resources or the state of processes. A deadlock occurs when there is a circular wait condition, where each process holds a resource that the next process in the cycle needs, leading to a situation where no process can proceed. The Petri Net structure can visually illustrate these interactions and the states leading to deadlock, allowing for analysis and identification of potential deadlock situations.
